Abstract

Waste of the special coke production called special coke fines was investigated as a raw material to produce a carbon adsorbent. The results of a study of the technical characteristics, X-ray diffraction phase composition, and structure of the special coke fines showed it is formed of the carbon and mineral dense non-porous particles and the carbon particles of a graphite-like structure. The carbon component was derived from coke fines varying the elutriation method parameters. The influence of steam–gas activation with live water steam on the sorption properties of the special coke fines and derived carbon materials was studied. The experiments showed that the best results were achieved using a two-stage activation process of carbon materials with live water steam. It was determined that prepared special coke-based carbon adsorbents had a high adsorption activity toward rhenium (VII) ions. The method of the production of the adsorbent based on the special coke fines is recommended, which includes separation of the special coke fines into carbon and mineral parts by means of elutriation in the mixture of kerosene and water with the subsequent two-stage activation of the carbon material with live water steam.
